Hurricane Sandy has often been compared to Hermine, but there are some major differences. Sandy started losing tropical characteristics after reaching the Bahamas, but it redeveloped convection near the center, and was still tropical after the hook northwest.

(edit: added later) The Perfect Storm/Halloween storm of 1991 was an extratropical storm that brought high waves to much of the eastern United States, resulting in widespread disaster declarations and beach replenishment projects. The storm moved over the Gulf Stream while looping and transitioned into a hurricane, but unlike Hermine it went to the northeast (and was later in the year).

Shows a worst-case scenario if a storm comes from Florida and curves back to the northwest. Agnes tapped into that moisture and caused severe damage in Pennsylvania and New York.

A hurricane strike on Florida, check. Weakening and moving NE into Georgia, check. Curving back to the northwest, check.

It struck Florida a little more to the west, but it hugged the Atlantic coast up to North Carolina. It re-intensified into a hurricane and hooked slightly leftward, hitting New England.
